Parking lights remain on and off

As I mentioned in the title of the friends, the parking lamps remain open .. My vehicle has a headlight sensor .. everything is activated in the dark, it is not lit in the daytime ... I put the battery terminal on again, it is still lit. thanks..

In the 307s, there is the role and insurance control panel on the battery side called BSM. There is a high probability that water will run there or there will be a short circuit. Take a look at it.

My cousin had a light bulb on his left, which was left on at first.
Then the right signal remained on. We changed the BSM brain.

Thank you Ali Ali for the answer ... It is hard to be a situation like entering water, neither it rained nor the car was washed.
